If the perimeter of the following triangle is 7x-2 what s the length of the unknown side
3x
3x - 4
4
3x + 4

ANSWER

The unknown side is 3x units.

EXPLANATION

Let the unknown side be y units.

Then the perimeter of the triangle is

It was given that, the perimeter is 7x-2.

This implies that,

We solve for y to get,

Simplify to get;

d

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
